Summary
CVE-2023-36812 is a critical-severity Injection (CWE-74) vulnerability in Opentsdb. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
OpenTSDB, an open source distributed time series database, contains a remote code execution vulnerability tracked as CVE-2023-36812. The flaw arises when user-controlled input is written into a Gnuplot configuration file that is subsequently executed by the Gnuplot binary, enabling arbitrary command execution. The issue is rated 9.8 on CVSS 3.1 and is classified under CWE-74 (Injection). It was addressed in release 2.4.2 through commits 07c4641471c and fa88d3e4b.
Unauthenticated attackers with network access can exploit the vulnerability without user interaction to obtain full control over the affected OpenTSDB instance, including the ability to execute arbitrary commands on the underlying host. The attack surface is exposed whenever the Gnuplot integration is reachable, which occurs by default in vulnerable configurations.
Public advisories and the project repository recommend upgrading to version 2.4.2. Where immediate upgrade is not feasible, operators can set tsd.core.enable_ui to true and delete the mygnuplot.bat and mygnuplot.sh shell scripts to disable the affected code path. The current EPSS score of 0.8429 with a recorded peak of 0.8559 indicates sustained exploitation interest following disclosure.

Secure coding standards require proper neutralization of special elements, directly addressing CWE-74.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-74, a class-level weakness, and none of its children carries one either.
